Can a bout of exercise harm the human heart?

This commentary discusses a study by Stewart et al. (2016) that examined the effects of acute endurance exercise on cardiac function in recreationally active men. Participants performed two cycling trials: 90 minutes at heavy intensity and 120 minutes at moderate intensity. Findings indicated transient reductions in left and right ventricular

Compact Arterial Monitoring Device Use in Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA): A Simple Validation Study in Swine

This 2024 study evaluated the accuracy of a compact, disposable pressure monitoring device (Compass™) used during partial REBOA procedures in a swine model. Four Yorkshire pigs underwent induced hemorrhagic shock followed by REBOA with the Compass™ transducer. Mean arterial pressures recorded by the device were compared to standard arterial line

Bone Health After Exercise Alone, GLP-1 Receptor Agonist Treatment, or Combination Treatment: A Secondary Analysis of a Randomized Clinical Trial

This 2024 secondary analysis of a randomized clinical trial examined the effects of exercise, GLP-1 receptor agonist (liraglutide) treatment, and their combination on bone health in adults with obesity. After an initial 8-week low-calorie diet, 195 participants were randomized into four groups: exercise alone, liraglutide alone, combination of both, or

This 2021 review explores the therapeutic potential of mesenchymal stem cell-derived exosomes (MSC-Exo) in treating neurocognitive disorders such as Alzheimer's and Parkinson's diseases. MSC-Exo are nano-sized extracellular vesicles enriched with neuroprotective and immunomodulatory molecules, including microRNAs, neural growth factors, and anti-inflammatory cytokines. These exosomes can cross the blood-brain barrier, attenuate
This 2023 review explores azelaic acid (AzA), a naturally occurring dicarboxylic acid with multifaceted dermatological applications. AzA exhibits anti-inflammatory, antimicrobial, antioxidant, and anti-keratinizing properties, making it effective in treating conditions like acne vulgaris, rosacea, melasma, and post-inflammatory hyperpigmentation. Its mechanisms include inhibition of tyrosinase and mitochondrial enzymes, suppression of DNA
This 2022 randomized controlled trial compared the effects of three emollient creams—urea-glycerol cream (UGC), glycerol cream (GC), and paraffin cream (PC)—on skin barrier function in adults with atopic dermatitis (AD). Over four weeks, UGC significantly improved skin barrier integrity, reduced transepidermal water loss (TEWL), and increased natural moisturizing factor (NMF)
This 2022 study evaluated the moisture-retention capacity of glycerin solutions at concentrations ranging from 0% to 100% using gravimetric analysis, transepidermal water loss (TEWL) assessment, and differential scanning calorimetry (DSC). Results indicated that moisture retention improved with increasing glycerin concentration up to 60%, with minimal weight change observed between 60%
This 2024 narrative review evaluates the efficacy and safety of various oral supplements and topical adjuvants in mitigating mucocutaneous and musculoskeletal side effects associated with isotretinoin therapy. Oral supplements such as omega-3 fatty acids, vitamin E, folic acid with vitamin B12, antihistamines, L-carnitine, biotin, and combination supplements were found to
This 2005 study conducted two double-blind, vehicle-controlled trials to assess the histological effects of a topical formulation combining retinol and vitamin C on aged and photoaged human skin. In the first study, eight postmenopausal women applied the formulation to one elbow and a vehicle to the other twice daily for
This 2019 review discusses the impact of estrogen deficiency on skin aging in postmenopausal women, highlighting symptoms such as dryness, atrophy, fine wrinkling, and poor wound healing. The article evaluates topical treatments, including estrogen creams and soy-derived isoflavones like genistein, which interact with estrogen receptors in the skin. Clinical studies
This 1998 study evaluated the effects of topical estradiol (0.01%) and estriol (0.3%) creams on skin aging in 59 perimenopausal women over six months. Both treatments significantly improved skin elasticity, firmness, and moisture, with reductions in wrinkle depth and pore size ranging from 61% to 100%. Immunohistochemical analysis revealed increased
This 2018 review by Pickart and Margolina explores the multifaceted biological activities of the GHK-Cu peptide (glycyl-L-histidyl-L-lysine bound to copper). GHK-Cu modulates gene expression, upregulating genes associated with tissue repair and downregulating those linked to inflammation and cancer progression. It promotes collagen and elastin synthesis, enhances skin firmness, reduces wrinkles,
